[Pseudophakia in children with juvenile arthritis].

BACKGROUND

Cataract secondary to juvenile rheumatoid arthritis is a severe, vision-threatening complication in early childhood. Intraocular lens implantation is controversial. The follow-up of four pseudophakic eyes of three patients and their perioperative therapeutic regimen were retrospectively analyzed. Early and late postoperative complications are reported.

PATIENTS AND METHODS

Both girls had lens aspiration and posterior lens implantation at the ages of 6 and 12 years, the boy at the age of 10 and 14 years. All patients had relapsing anterior uveitis. The follow-up time was 3 years (1-6 years). One girl was diagnosed with sarcoidosis, causing juvenile arthritis. Both girls had perioperative methothrexate and prednisolone therapy. The boy had azathioprine therapy at the time of his first cataract surgery; later he had no systemic therapy. Both girls' intraocular lenses were implanted at different eye hospitals.

RESULTS

Both girls had severe inflammatory reactions after surgery. At the hospitals both eyes had surgical revision for iris capture. In one case this was combined with exchanging the intraocular lens. Iris capture persisted for this eye and later vitrectomy with silicone oil filling was necessary to delay phthisis, resulting in amaurosis. For two pseudophakic eyes vitrectomy was necessary later because of severe vitreous opacities, but visual acuity was severely diminished by chronic cystoid macular edema and epiretinal membranes. The boy developed in his second eye intermittent iris bombata and persistent secondary glaucoma, visual acuity was stabilized at 0.5.

CONCLUSIONS

Secondary cataract due to juvenile rheumatoid arthritis or sarcoidosis is a difficult situation for phacoemulsification with intraocular lens implantation in children. For severe inflammatory complications intense local and systemic anti-inflammatory therapy is mandatory. Visual prognosis is reduced for the uveitic posterior segment and glaucoma complications. IOL implantation can be recommended for only a very few patients.
